Thanks to the web, here are some photos:

The Smart-UPS 420 is the stepped wave model I was thinking of earlier. 
Also, I have seen what I think is that second unit, the Back-UPS XS 
1300, working acceptably well with a FreeBSD system.

The Smart-UPS 1000 shown last is functionally similar to the SUA1500. 
The differences are number and size of batteries and inverter capacity. 
The SUA1500 has both serial and USB connection.  Some of the older, 
smaller APC units are serial only.

Finally, sysutils/apcupsd lets you connect one computer to the UPS 
directly and act as a server.  Other computers can be powered off the 
same UPS and interact with the server over the net.
